It doesn't have to be currently running, of course. Just your current favorite, even if the show has already run its entire course. And "TV show" is a bit of a misnomer these days, since lots of people don't even watch series on televisions anymore, and many series don't even air on television.
But you know what I mean. Anything airing on TV, as well as original streaming programming, counts.
My current favorite is Better Call Saul, about which I was doing a little tweeting last night. Rhea Seehorn, who plays Kim, is perfection, and Kim has to be one of my favorite characters of all time. And although I'm singling her out, literally everyone is great. The whole show is great.
The acting, the writing, the direction, the cinematography, the costuming, the set design. All of it. Exquisite.
Breaking Bad and now Better Call Saul absorb me in a way no other shows ever have. There are times I don't realize I'm holding my breath until I exhale at the commercial break.
I even have Saul to keep me company on my desk! (He isn't typically standing on the keyboard of my laptop, lol, but he's always on my desk.)
Anyway! What's your current fave?
